The Venturi effect describes how the velocity of a fluid increases and pressure decreases as it passes through a constricted section of pipe. According to fluid dynamics laws, velocity must increase through a constriction while pressure decreases to maintain continuity and conserve energy. This effect can be measured using a Venturi tube, which is a length of pipe with varying diameters and entry and exit cones designed to minimize drag.
Ventury effect is present in most important systems within the maritime industry which includes dredgers, pumps and waste disposal. But how does it work and what dynamics and laws govern its operation.

This publication is intended for engineers seeking an introduction to the problem of water hammer in pumped pressure mains. This is a subject of increasing interest because of the development of larger and more integrated sewer systems. Consideration of water hammer is essential for structural design of pipelines.

the presentation upon the measurement of the flow of fluid by the venturimeter and the pitot tube and pipe orifice . also include the type of the pitote tube . this instrument is used to measure the flow rate of the flow of fluid.
Flow in super critical state is an unstable type of flow. It has a tendency to transfer n to sub critical flow. Flow depth is small in a supercritical state. which increases suddenly while changing the subcritical state. This phenomenon sudden increase in depth of flow is called a HYDRAULIC JUMP.

2. The Venturi effect is a jet effect; as with a funnel the
velocity of the fluid increases as the cross sectional area
decreases, with the static pressure correspondingly
decreasing. According to the laws governing fluid
dynamics, a fluid's velocity must increase as it passes
through a constriction to satisfy the principle of
continuity, while its pressure must decrease to satisfy
the principle of conservation of mechanical energy.
Thus any gain in kinetic energy a fluid may accrue due
to its increased velocity through a constriction is
negated by a drop in pressure. An equation for the drop
in pressure due to the Venturi effect may be derived
from a combination of Bernoulli's principle and the
continuity equation.
3. The limiting case of the Venturi effect is when a
fluid reaches the state of choked flow, where the
fluid velocity approaches the local speed of sound.
In choked flow the mass flow rate will not increase
with a further decrease in the downstream pressure
environment.
4. The simplest apparatus, as shown in the
photograph and diagram, is a tubular setup known
as a Venturi tube or simply a venturi. Fluid flows
through a length of pipe of varying diameter. To
avoid undue drag, a Venturi tube typically has an
entry cone of 30 degrees and an exit cone of 5
degrees.
5. The Venturi effect is the reduction in fluid pressure
that results when a fluid flows through a
constricted section of pipe.
Fluid flows through a length of pipe of varying
diameter. To avoid undue drag, a Venturi tube
typically has an entry cone of 30 degrees and an
exit cone of 5 degrees.
